To all 'whom it may conaem:

Be it known'that I, ALEXANDER IADMSQ'SY,

'a citizen of the. United States, residing at- Akron, in the county of-.Summit and State ,of Ohio,.have invented Anew andusetul Im- .prpv'ementsr in VulcanizingfMolds, of vwhichthe following is a'specification.

This invention relates to vluloanizers forv -gths of hose, tubing,

elastic tiles, an the like.

. eretofore, A'such `articles as hose, tires, etc., have been, 1n a 'large measure, vulcanized in short'-'standard' lengths' and where such articles as] rubber. tires,- fwhich 'are usually vvulcanized the fact` that" lthe lengths 'requiid -lb purchaser will'notgbgpqua1n Y A stances tO-thevstandard length/ofthtire and hence," the 'surplus' is Q was'te,L-there\byg I causing a loss either to the dealer ,orthepur-j chaserf` A y, e .Thev object of this invention therefore, is

-to provide a suitable vulcanizer for manu-Vv facturing 'articles in cntinuous'flengthe,

such as five hundred to one thousand feet,

.f tubing, hose, or rubber 4tiresi atone opera:-

tion, and which can, after-being made,`beV reeled upl andshipped tothe dealer' and short lengths be cut orfseveredfor the retail trade, thereby. eliminating'. -the waste' due to the manufacture of the lengths hereto-N. fore u sed. I att-am this object' by providing a vulcanizer provided4 with a spirally-arranged groove in which comparativelylong lengths 'of rubber articles' can be etlcctually vulcanized without employing an unneces- With the foregoing 'and other objects in View, the invention consists in thenovel construction, combination and arrangement of parts constituting the invention to be here matter speoifcallyrdescribed and illustrated in ,the accompanying drawings which form a. part hereof, wherein is shown .the preferredembodiment of theinventiontbut it 4 in approximate] iifteen-foot'lei'i'gths, are sent tojtheretail-- dealer there. is a 'considerable waste" due'tof the manyfini' Specication of Letters Patenti?. 5 @Falten-ted Sept- 39 1912.

fe-rent figures, Figure 1, is a'plan of a vulcanizer embodying this invention; Fig. 2,

is asectional view online X of Fig'. 1; Fig.

3, is asimilar view Online Y of Fig'. l; and, 'lf`1g. 4, is a', plan :view enlarged -of a portiongofvthe vulcanizer with parts thereof broken 'away to more fully illustrate the invention.-

" "lhe: invention embodies a plurality pairs of upper and llower mold-sections adapted to be abutted together to 'form an' endless vulcanizer, and in the drawings the vreference numerals 1, 2,3 and 4 denote the upper moldsections Aeach of which are prouded atthelr ends V with daring'. anges 5,

"tlielflanges of contiguous sections arranged to' clamped" together by clamping-bolts 6, so'. thattheentire` 'upper' hal-f of the vulcaiiizerisnnited and may be raised or lowered asfa vunitarystructure.V The end flanges 'fzare p ret:rablyfst,1 lenefdy by means of webs .7`and' the sections"v are further strengthened by up ardly-exten'cling lianges 8 arranged Vat".intervals.'- Xt-"suitable" points on the upper face of the mold-sections 1-4 inclusive, are upwardly-extending" apertured fianges il, provided withl strengthening bosses 10 to which are 'secured by means of hold-fast devices 411 lifting links 12 by which suitable tackle may be ,connected with the upper fha-lf of the vulcanizer 'for raising and lowerso'A ing vthe salue. The upper mold-sections are also' provided'with- ,a plurality of pairs of laterallylezgtending `lugs 13"spac`ed from ,'each other to provide between the'm openings t`o receive clamping-bolts, and it may ybe stated that while only va few of these pairs of lugs are shown, the' number of pairs 'of lugs may be lncreased as de's1red. The

interiors of each of the sections l-.4 incluf. Y'

sive, Vare provided with-cavities or openings in one vsection may be connected with the cav` ity in anothersection', that isto say, the cui tlre cavity in the upper half of the 'vulcanize'r may be continuous land'heated by an' inlet-pipe 15 and drained by an outlet-pipe' 16, or cach section m'ay be providedwith its respective inlet 'and drain-pipe, in the latter case, the ends of the moldfsections `shown in Fig. 2 will be closed instead of open. In the lower face of theA moldsec tions 1-4 inclusive, are a plurality'of longi:

tudinal: grooves' 17, a more particularfde? A.1,037,187 l i'.

A izer composed of the members 1-4 inclusive, are the lower or complementary members22 ofthe devicewhich are usually sup orted by legs ll8, 'and each embodies a -mo d-section corresponding incontourvwith' its respective superposed upper` section, and thel lower' Asections are alsolprovided witn's'trengthenscribed with respect to the upper moldmembers. The interior of each of 'the lower moldesection's v22 are provided with openings constituting steam-chambers 23 similar in all respects to the steam-chambersl in the upper members of the mold, and the chambers incoadjacent sectionsmay communicate` so as tomake a continuous opening throughout the. lower portion of the vulcan izer or `each may be: supplied separatelyA .witha heating medium such as 'steam and also provided with a drainage-tube to carry away the products of condensation. The

provided with longitudinalgrooves .24.- to register with the complementary grooves 17 in the upper section to' ifo'rur continuous mold-cavities. .The upperportion of the vulcanizer isr adapted Ato 4be brought` -irit'o lregistering relation with* respect td the The mold-cavities formed by ing grooves 17 and 24 are shaped to impart the desired configuration vto the. articles to.

be vulcanized andfwhile the drawings show cylindrical mold-cavitie'sit will beapparent that they maybe given any. otherfconfgu'ra tion desired.

At a suitable point, say, for, instance, near Y the joint betweenthe mold-sections 2 and 3, there 1s provided' on the upper moldsection cavity 27 vin the upperl section2 and its lower 3 and its complementary f lowermember' laterally-extending lugs 26 provided with a cavity which registers' with the moldmember, and this cavity 27 extends around the entire vulcanizer spirally so as to form the registei'-,

convolutions vwhich terminate at the point 28 onlthe opposite side from the lug 26.

-The upper mold-member 2 and Aits complement'ry member areprovided with a 4laterally-extending. lug 29 providedwith a moldcavity which communicates .with the end 28 of the groove27. From this it will be seen that Afrom the mold-cavity in the lug 26 and extending throughout the entirev contacting faces of the mold-sections is a spirally-arranged groove 27 terminating with the niold-cavlty in the lu 26. so as to make a continuous mold-forming opening of great length.l

ln'filling the-mold the unvulcanized rubber stockv 1s placed in or started from the mold-cavity in either the lugs 26 or 29 and carried continuously around the -vulcanizer 1n the mold-cavity 27 untllit terminates in the cavity in the opposite lug. The upper half of the vulcanizer consisting of the members l-4 inclusive, is then lowered to position 'and clamped -in position through 1 the medium of clamping-bolts 3l placed in the 'notches between the pairs of lugs 13, and these ybolts also extend. through similar notches formed by pairs of lugs 27 in lver- Itical alinement on the -lower -rnold-'sections- After vulcanization has taken place the clamping-bolts -31 are removed and thelupper .half of' the 'vulcanizer raised and the cured article removed. "lgclaim: c Y

A vulcanizer comprising upper.and lower portions each composed of a'pluralityv of separable connected portious, said upper portion movable bodily from said lower portion, the opposing faces of said portions provided' with continuous uninterrupted registering.groovesl arranged in .a series of horizontal spirally formed convolutions forming a continuous mold cavity, the terminiofsaid cavity arrangedon opposite sides of said convolutions and being open, the groovesI lying in a horizontal plane` throughout-'and in the same plane as the` open termini.-

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
